To respond to the "it's illegal" comments, it was only illegal until 2005 due to people thinking that the wormwood had hallucinogenic properties. It hasn't been illegal for 6 years. I have a large bottle of it myself at home which I picked up from a local liqueur store. No back-alley dealings or imports of any kind. Just stopped in a store and bought it.
As for the taste: tastes strongly of licorice and burns all the way down to your stomach.
